본 연구는 자메이카와 한국과의 통합적 그리고 방어적 인상관리 행동 및 자신을 표현하고자 하는 행동에 있어서의 두 나라간 차이를 연구하였다. 인상관리행동에 관한 선행연구와 문화관련 연구들은 문화에서의 차이점들은 인상관리행동의 스타일을 결정한다고 주장하고 있다. 따라서 본 연구는 자메이카와 한국 문화 중 어떠한 요소들이 구성원들이 좀 더 인상관리 행동을 하는지 그리고 다른 국가 간 문화적 차이를 토대로 어떠한 인상관리행동의 차이를 보이는지 연구하였다. 자메이카와 한국의 102 명 개인을 대상으로 설문 조사한 결과 양 국가에서의 인상관리 행동은 비슷한 점과 다른 점 두 가지를 모두 확인하였다. 비록 본 연구에서는 여러 제한점에도 불구하고, 본 연구의 두 국가 간 문화차이로 인해 조직 내 구성원들의 인상관리전략이 다르다는 것을 확인하였다. 특히 한국은 자메이카보다 좀 더 인상관리를 중요시 여기는 것으로 나타났다. 또한 자메이카는 방어적인 인상관리 행동을 높게 사용하는 반면 한국은 자기프로모션과 통합적 인상관리 전략을 좀 더 많이 사용하는 것으로 나타났다.

The purpose of this study is to determine and compare the mechanical and flow properties of polyvinylsiloxane impression pastes. Twelve polyvinylsiloxane impression materials were used. As mechanical properties, tensile strength and tear resistance were measured. Impression materials are subjected to tensile stresses when they are removed from the oral cavity and from stone models and tear resistance is the ability of the material to resist tearing under a tensile stress. Flow is dependent on the ability of the material to resist shear forces. Flow tests were performed to determine the handling characteristics and was measured using a shark fin testing device. An impression material must be able to penetrate the narrow subgingival sulcus and tight interproximal areas. Therefore, it must be able to resist the shear forces as it is pushed between tooth and gingival walls. It is necessary to understand the properties of interocclusal recording materials and is considered that the results obtained in this study will provide guideline information for the manufacturing of impression materials and for selecting appropriate impression materials.

This study was designed to investigate the fitness of adjustable dental impression trays. The size and shape of these trays were designed from the results of the dental arch size of Korean adults. Tray samples were made by CAD-CAM working. A hundred dental students(male:50, female:50) were selected for taking irreversible hydrocolloid impression using these trays. The author measured the width and length of impression material on the several measuring points. The results obtained were as follows : 1. Uniform impression material thickness was achieved by controlling the width of the tray using stops and beveled guides. 2. In the upper tray, the impression material thickness was measured to be rather great showing thickness of the labial vestibule 8.3 mm and the midpalatal part 8.6 mm. 3. In the lower tray, length of the impression material of the labial vestibule of first, second premolar contact point was 7.8 mm, and thickness of the lingual part of premolars(1.8 mm) and molars(1.9 mm) showed small values. 4. In the lower tray, the impression material thickness of the buccal shelf area(0.2 mm) and the retromolar pad area(0.6 mm) was measured to be too small.

Niveteen stimulus photographs varied in hue and color scheme of one clothing style of Korean dress worn by a female were used to explore the differences in perceptive effect of clothing cues(color, color scheme, structure) on impression formation and graduate students. The data were analyzed by factor analysis, factor score, ANOVA and Scheffe-test. Results indicate perceptive effects of clothing cues on impression formation are influenced by gender-differences and major-difference of perceivers. Significant gender differences were found in perception of clothing cues on impression effect. Interaction effects were found between clothing cues and gender. Significant major differences were found in perception of clothing cues on impression effect. Interaction effects were found between clothing cues and perceiver's major. Female perceivers and perceivers of major-ing in Liberal Arts reacted to clothing cues on impression formation with greater sensitivity than male perceivers and perceivers of majoring in Natural Sciences. Frequent interaction effects between gender and color of China (cool-warm color), between major difference and color scheme(related color harmony-contrasting color harmony) appeared on factors of impression effect. The influence of perceiver variables on their perception of clothing cues for impression effcet has important implications for gender difference and perceiver's maforing backgroung in a social situation.

The objectives of this study were to identify the dimensional structure of female impression formation based on ornaments and color of jacket, and to analyze the effect of ornaments, color of jacket, and perceiver's gender on impression formation. The experimental design was 3$\times$4$\times$2(ornaments$\times$color of jacket$\times$gender) factorial design by 3 independent variables. The stimuli of color photographs of female model and the semantic differential scale were used. Samples were 288 college males and females. The data were analyzed by factor analysis, ANOVA, duncan's multiple range test, and t-test. Four factors derived to account for the dimensions of impression formation. These were potency, elegance, evaluation, youthfulness, and feminine. Wearing of large ornaments(a necklace and earrings) had a negative effect on impression of elegance and positive on potency. Red jackets increased the impression of positive evaluation, potency, feminity, and youthfulness. On the jackets of achromatic color such as white and black, wearing of large ornaments increased the effect of potency, and large ornaments increased matured impression on black jacket. The results of this study mean that perceiverss used large ornaments and red jackets as a salient cue.

This study investigated the polymerization inhibition effect of latex gloves on addition silicone impression material. Three different kinds of addition silicone impression materials and a natural latex gloves were used in this study. The results were as follows. 1. Compared to the control group, all of those three kinds of impression materials took longer curing time in order of unwashed, alcohol and washed group, on the other hand, degloving group had shorter curing time than control group(p<0.05). 2. By the type of impression materials, there was no significant difference observed between Exafine and Twinz in ungloved group, Exafine and Imprint II in unwashed group, and Exafine and Twinz in degloving group(p>0.05). 3. The degree of polymerization at 6 minutes after mixing impression materials was evaluated by dividing its range into score 1 to 5. All of the impression materials got score 5 in control group and degloving group, which implies perfect polymerization. In unwashed group, most of them appeared to be score 2 while score 3 were most frequently observed in alcohol group and score 4 in washed group. Thus each group showed differences in the degree of polymerization(p<0.05).

A dynamic impression is a functional impression that records the functional movement of the patient's own muscle and muscle attachment. This process reduces the number of random factors. This article describes a method for making a special tray using a dynamic impression concept that was made from provisional dentures used for implant healing. The individual tray is used to make a wash-impression to record the features of the mucosa in detail. The main advantage of this technique is that it provides a functional relationship of the implant components to the supporting tissues without overextension because provisional denture had been used for 2 months and the border length of individual tray was nearly the same as that of provisional denture. The delivery of the prosthesis constructed using this impression technique is time-saving because there is no need for border molding and there are fewer post-insertion appliance adjustments.

The purpose of this study is to inquire about the effects of individual tray design and impression method on the border extension and contour of denture. 10 students at the dentistry college who have normal occlusion and symmetric facial form and normal facial muscle activity were selected. The tray was designed three types (large, medium, small tray). After border molding was done by dentist and operator, final impression was taken. The length of impression body and width of border were measured by a vernier caliper on the cast. The obtained results were as follows : 1. As the tray border was shortened, the length of impression body and width of border was short (P<0.01). 2. When the impression was taken with the small tray, the length of impression body was short in passive border molding than active border molding. 3. When the medium tray was used, the width of impression body was short in passive border molding than active border molding.
